3 daysos/amd64: Reduce coupling with VAS structureIan Moffett
This commit moves the VAS structure into a standard MD layer side and makes it accessible through a standard MI layer header. This indirection reduces coupling so that the codebase wont break if a name change or anything is needed. Signed-off-by: Ian Moffett <ian@osmora.org>
3 daysos/amd64: Make MMU header standard per archIan Moffett
Lunos's virtual memory system is split into two parts, the machine dependent MMU layer and the machine independent layer. The MMU side exposes a standard bridge header that allows the MI layer to interface with the MD layer. Signed-off-by: Ian Moffett <ian@osmora.org>

4 dayskern: vm: Implement page mapping and VASesIan Moffett
This commit implements an interface to allow other parts of Lunos to talk to the MMU: - Added the 'vas' structure as the virtual address space - Added MMU specific prot flags - Added mmu_map_single() to map pages - Added mmu_this_vas() to grab the current VAS ...
